The Schneider Electric ENW33116 is a rear connection accessory for the EasyPact NW range of air circuit breakers. It is a 4-pole drawout connection rated for 630 to 1250 A, mounted at the bottom of the breaker cradle.
Drawout mounting means the breaker slides into a fixed cradle; the rear connection stays in the panel while the breaker unit can be racked out for maintenance or replacement without disturbing the power wiring. This is the standard configuration for switchgear where uptime matters — you swap the breaker, not the connections. Bottom mounting with horizontal and vertical connection positions gives flexibility in cabinet layout. The rear connection location keeps cables out of the breaker compartment, which simplifies arc-flash boundary management during racking operations.
